I was able to get close to the lands with my Howa .243 and a hinged floorplate.
I tried the TTSX, TSX, 100 grain Hornady flatbase spirepoint, and 100 grain Sierra Pro-hunter. That rifle liked the TTSX best, well after the Hornady bullet, but it has been discontinued....
All of the Cup-N-Cores were no problem seating at .010" off the lands and the TTSX/TSX were seated .050" from the lands, and I had some room in the magbox.
That rifle became a .308, and right now the floorplate mag is gone in favor of a DBM. I am able to seat the bullets I use now at just .010" from the lands but if I go to a sleeker bullet, the floorplate setup will have to go back on if I want to stay close. Even then, they may have to jump because the internal magbox is only .080" longer.
Floorplate mag allows a .243 (or .308) to go 2.890", maybe some change, but the DBM is 2.810". There's obviously more latitude for a .243, more so than a with the .308 cartridge.
But, so far, everything has fit, but I haven't tried any real slick bullets, either.
OK, I looked in my notes.
Floorplate magbox allowed 2.890, TXS at .050" off lands were 2.665", TTSX OAL was 2.667" same distance from the lands, Hornady Spirepoint OAL 2.682" at .012" from the lands, and the Sierra was at 2.650 at .010" from the lands. Plenty for the .243 and the bullets I used, but 2.890 isn't alot of room for a .308...
